I am a developer who moved from Windows, to Linux, to macOS, to Linux. A typical developer’s journey 😆. So moving from windows to Linux was over 13-14 years ago. I didn’t do much from the windows world other than games and single executable files. But moving from macOS to Linux, has been a bit tough. KDE has been able to provide me with everything I want and more. The one thing that I missed the most was the emoji keyboard, with easy to launch shortcut.

My usage of emoji was at its peak during macOS days, I used emoji for my communications, commits, function name and even terminal aliases. 😈 Not everyone was a fan of my emoji usages, but I loved it.

Note: I am using Apartment gem to manage my multi schema database, and this article is written with expectation you know and use that gem.

When you have multiple schema in your rails application, it is important for them to remain consistent. Rails migration is run by keeping track of the timestamp prefixed in front of its file name. It stores the database. So when you restore a schema that hasn’t ran the migration, but rest of the schemas has it, rails thinks it has already ran the migration. Rails look at the main / default schema to know if it has ran the migrations and then follow up on the rest.

Accessing the list of commands you have ran in your irb or rails console.

Running the following command in your console Readline::HISTORY.to_a returns the array of commands you have typed in console. After which you can treat it like any other array in ruby - search, sort, etc.

This tutorial or concept uses two softwares to make remote coding on your home machine possible.

1. Tailscale
2. code-server

Tailscale is basically a VPN using open source wireguard protocol. It creates an encrypted point to point connection so that only your devices can talk to each other.

So you can build a secure connection between your two computers over the internet. These two computers can be across the world, and they will be as if they are on a same network.

When we create a new server in aws, it allows us to generate a key pair and attach it to the server. Now imagine you want to share access to this multiple people in your team, but you don’t want to share your private key. This is what you need to do.

• Generate new key for each member of your team or ask each member for there public keys
• Add it to the authorized_keys list in your servers .ssh folder
